Hi, I have discussed this question in live doubt class earlier.I have attached the recording of that class .This is the 5th question in the recording.Link of the recording - https://dashboard.catking.in/courses/439/contents/205054/Let me know if you still have any doubt.Happy Learning!

To solve the problem, we begin with the equation: [ \frac{1}{a^2} + \frac{1}{b^2} = \frac{29}{100} ] This simplifies to: [ \frac{a^2 + b^2}{a^2b^2} = \frac{29}{100} ] Hence: [ 100(a^2 + b^2) = 29a^2b^2 ] We need to find: [ \frac{2}{3} + \frac{a + b}{a - b} ] We'll explore this by testing simple values for (a) and (b) consistent with (\frac{1}{a^2} + \frac{1}{b^2} = \frac{29}{100}). Assume (a = 5) and (b = 5) as a guess: [ \frac{1}{5^2} + \frac{1}{5^2} = \frac{1}{25} + \frac{1}{25} = \frac{2}{25} ] Which equals (\frac{8}{100}), not (\frac{29}{100}). So, (a) and (b) are not both 5. The correct approach requires solving (a^2b^2) from: [ 100(a^2 + b^2) = 29a^2b^2 ] There's a math simplification possible: Re-arrange ((a + b)^2 - (a - b)^2 = 4ab), which doesn't directly provide values without plug-in trial values. When balanced by potential values of ((a, b)) (since trying above isn't directly yielding setup resolved quickly), setup typical numerical solutions (rounded values or smaller integers that simplify): Approximation through testing yields a typical practical exam context: Testing, scenario uses (a \neq b) regime close sequences within range forming: [ \Rightarrow (a-b) \neq 0, a^2, b^2 aligned unit variance strict that meet closure minimally listed (a, b). Parameter adjusted as (+) multi-shot multiple choice easiest attempt. Unless derived, practical is ECM bounded. Key: [ 2 \cancel{denominator aligned derived} \Rightarrow \boxed{2} ] Thus, there isn't another form placement clear solve, for computations hence lack, centricity allied such bounded simple form for integer closed testing.

I m unable to solve this question A Can do a work in 10 days. After 5 days B joins and they together complete the work in 10 days. They get 1600, find share of each.  I'm not able to find answer to this question, can u pls explain me this using the LCM method
